(Main)Vegetable oils - Determination of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) with online-coupled high performance liquid chromatography-gas chromatography-flame ionization detection (HPLC-GC-FID) analysis - Method for low limit of quantification (ISO 20122:2024)
Vegetable oils - Determination of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) with online-coupled high performance liquid chromatography-gas chromatography-flame ionization detection (HPLC-GC-FID) analysis - Method for low limit of quantification (ISO 20122:2024)
This document specifies a procedure for the determination of saturated and aromatic hydrocarbons (from C10 to C50) in vegetable fats and oils using the online-coupled high performance liquid chromatography-gas chromatography-flame ionization detection (HPLC-GC-FID). This document does not apply to other matrices.
The method is applicable for the analysis of mineral oil saturated hydrocarbons (MOSH) and/or mineral oil aromatic hydrocarbons (MOAH).
According to the results of the interlaboratory studies, the method has been proven suitable for MOSH mass concentrations above 3 mg/kg and MOAH mass concentrations above 2 mg/kg.
In case of suspected interferences, the fossil origin of the MOSH and MOAH fraction can be verified by examination by GC⨯GC-MS.
An alternative method for the epoxidation of the MOAH fraction (performic acid epoxidation) is proposed in Annex C. This alternative method provides comparable results to the ethanolic epoxidation of the MOAH fraction described in 8.6. This alternative method for epoxidation has proven to be efficient for samples with a high amount of interferences in the MOAH fraction (e.g. tropical oils).

Huiles végétales - Dosage des hydrocarbures saturés d’huile minérale (MOSH) et des hydrocarbures aromatiques d’huile minérale (MOAH) par analyse par chromatographie en phase liquide haute performance et chromatographie en phase gazeuse couplées à un détecteur à ionisation de flamme (CLHP-CG-FID) en ligne - Méthode pour une faible limite de quantification (ISO 20122:2024)
Le présent document spécifie un mode opératoire pour le dosage des hydrocarbures saturés et aromatiques (de C10 à C50) dans les matières grasses et huiles végétales en utilisant la chromatographie en phase liquide haute performance et la chromatographie en phase gazeuse couplées à un détecteur à ionisation de flamme (CLHP-CG-FID) en ligne. Le présent document ne s’applique pas à d’autres matrices.
La méthode s’applique à l’analyse des hydrocarbures saturés d’huile minérale (MOSH) et/ou des hydrocarbures aromatiques d’huile minérale (MOAH).
D’après les résultats des études interlaboratoires, il a été démontré que la méthode est adaptée pour des concentrations massiques de MOSH supérieures à 3 mg/kg et des concentrations massiques de MOAH supérieures à 2 mg/kg.
En cas de suspicion d’interférences, l’origine fossile des fractions MOSH et MOAH peut être vérifiée par un examen par chromatographie en phase gazeuse à deux dimensions, couplée à la spectrométrie de masse (CG⨯CG-SM).
Une méthode alternative d’époxydation de la fraction MOAH (époxydation par l’acide performique) est proposée dans l’Annexe C. Cette méthode donne des résultats comparables à l’époxydation éthanolique de la fraction MOAH décrite en 8.6. Cette méthode alternative d’époxydation s’est avérée efficace pour les échantillons présentant de fortes interférences dans la fraction MOAH (par exemple, les huiles tropicales).
